Woolfolk yarns combine the highest quality wool with ethical, sustainable practices. It's base fiber, Ovis 21 Ultimate Merino, comes from the innovative efforts of select wool farmers who care to responsibly steward Argentina's Patagonian Grasslands, and their special partnership with the Nature Conservatory and the outdoor retailer, Patagonia, Inc. The result is a unique fiber that feels more like cashmere than wool. 1% of wool profit goes back to Ovis 21.
